The utility model discloses a locking mechanism for plastic molding equipment, belonging to blow molding machine technology, including a locking cylinder. The mold clamping pull rod is designed as a hollow structure, and the telescopic rod of the core rod driving cylinder penetrates the locking cylinder and connecting flange in a sealed manner. The core rod passes through the hollow pull rod with sealed fit. A sliding block is arranged above the first inclined surface, the bottom of the sliding block fits the first inclined surface, and a pin with a preset angle on the side fits the second inclined surface. The structure adopts core rod telescopic locking and sliding block clamping positioning, achieving high-pressure mold clamping with uniform stress and stable locking performance, and ensuring normal mold opening and closing.
